The working chamsecured a disk G, formed in its face with a ber A of the cylinder A is connected by a recess G adapted to be engaged by a pin G channel A with a valve-chest F, in which is on an arm G fulcrumed in a casing G inmonnted to turn a rotary-valve F having its closing the disk G and secured on the shaft stem F extending through a suitable stuffing- ILprevionsly mentioned. A spring G presses 45 box carried on the casing F. The stem F the arm G and holds the pin G normally in has a connection G with a shaft H, mounted engagement with the recess G so that when to turn in suitable bearings and carrying a the shaft H is rotated the arm G and its pin bevel gear-Wheel H,in mesh with a bevel G carry the disk G around, thus rotating gear-wheel E", secured on the main drivingthe stem F and its valve F at the rate of one I00 50 shaft E, so that when the engine is runrevolution to two revolutions of the main ning normally thelbevel gear-wheel E, meshshaft E. On the outer end of the arm G is that when the engine runsat more than normal speed then the governor I by its stem I imparts a swinging motion to the lever G, so

that thebevel -G8 moves into the path of the bevel G7 to cause the arm G to swing against the tension of its spring G6 and to move the pin G out of engagement with the recess G \Vhen this takes place, the shaft H and the stem F are disconnected, and consequently the stem and valve remain stationary for the time being-tl1at is, during the time the lever G by its bevel (1} holds the arm G from dropping with the pin G into the recess G As the arm Gr rotates with the shaft H, it is evident that the bevel G leaves the bevel G8 duringpart of the revolution of the casing G the pin G then resting on the face of the disk Gr while the latter is stationary, and when the shaft II and the casing G have made a complete revolution and the bevel G is still in the previous position then the arm G is again prevented from swinging its pin G into engagement with the recess G It is evident that this takes place as long as the engine is running at a speed above a normal rate of speed; but as soon as the engine returns to a normal rate of speed then the bevel G swings out of the path of the bevel G and then the arm G swings to move its pin G in engagement with the recess G of the disk G. When this takes place, the valve F is again rotated in unison with the shaft H. The pin G recess G and port a are so arranged relatively to each other that the port a is in register with the port 0 at the time the pin G moves out of engagement with the recess G by the action of the governor-lever G", as previously described, so that during the time the'valve F is at a standstill its portaregisters with the port a and the exhaust-pipe K, while the port 1) is completely out off, (see Fig. 4,) and the charge of explosive mixture cannot pass into the cylinder for the time being.

The operation is as follows: \Vhen the engine is running and the port a registers with the port h, then the explosive mixture can pass from the pipe J, registering ports I) and a into the valve F, and from the latter into the working chamber of the cylinder A by way of the channel A When the desired quantity of explosive mixture has passed into the Working chamber A, then the port a has moved out of register with the port I), and then the piston B during its return stroke compresses the explosive mixture,after which an explosion takes place by a spark from the igniting device-that is, on the member L leaving the member L. The explosion sends the piston B on its working stroke to impart a rotary motion to the shaft E, and during the time the explosion takes place the port a is out of register with both ports I) and 0; but as soon as the piston B nears the end of its working stroke then the port a registers with the port 0, and the products of combustion can now escape from the working chamber. During the return stroke of the piston the products of combustion are completely expelled from the cylinder, and during the next inward stroke of the piston B the port a moves from the port 0 to the port I), and a new charge of explosive mixture passes into the cylinder, to be compressed therein on the return stroke of the piston I). The abovedescribed operation is then repeated.

In case the engine runs at a high rate of speed then the governor I acts on the lever G9 and the connection G, previously described, to disconnect the shaft H from the stem F so that the valve F remains stationary for the time being and in such position that the port a registers with the exhaustport a. When this takes'place, the working chamber is connected with the atmosphere and theproduets of combustion pass out of the cylinder and without subsequent compression during the compression period, and the explosive mixture is completely shut off from the engine until the speed is reduced to a normal rate.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. An explosive-engine having a rotary valve provided with a port adapted to alternately register with an inlet-port and an exhaust-port, and havingits stem provided with a disk having a recess on its face, a revolnble shaft, a pivoted and spring-pressed arm carried by the shaft and provided intermediate of its ends with a pin adapted to enter the disk of the valve-stem, and a lever for engaging the end of thelsaid arm to operate the same, said lever being under the control of I the governor, as set forth.

5. In an explosive-engine, a Working chamber, a valve-chest, a channel connecting the chest and chamber, a rotary valve having a port adapted to alternately register with an inlet-port and an exhaust port, a driving mechanism for the valve, a governor controlling the driving mechanism and an igniting device comprising a member projecting from the center of the valve, and a spring-pressed second member secured in the'head of the cylinder and extending through the said channel into the valve-chest and into the path of the member carried by the-valve.
